Title: Automated feedback and continuous learning for query optimization
Inventor: Vincent Corvinelli
IPC: G06F17/00
Filed: 2021-06-16
Abstract: In an approach to improve query optimization in a database management system, the methods identify opportunities for improvement in a cardinality estimate using a workload feedback process using a query feedback performed during query compilation. The methods identify correlations and relationships based on the structure of the query feedback and the runtime feedback performed, and collects data from the execution of a query to identify errors in estimates of the query optimizer. Further, the methods submit the query feedback and the runtime feedback to a machine learning engine to update a set of models. Additionally, the methods update a set of mode-s based on the submitted query feedback and runtime feedback, and output a new, updated, or re-trained model based on collected data from the execution of the query to identify the errors in estimates of the query optimizer, the submitted query feedback and the runtime feedback, or a trained generated mode.

Title: Permanent-magnet fault-tolerant in-wheel motor based on active sensorless strategy and drive and design methods thereof
Inventor: LI ZHANG
IPC: H02K1/2786
Filed: 2022-09-29
Abstract: A permanent-magnet fault-tolerant in-wheel motor based on an active sensorless strategy, comprising a rotating shaft 11, stator 9, and rotor 10 that are arranged in order from inside to outside. The stator comprises a yoke 22, armature teeth 14, slots 21, and fault-tolerant teeth 13. The armature teeth and fault tolerant teeth are evenly spaced along an outer circumference of the stator, where two adjacent armature teeth are isolated by one fault-tolerant tooth. Main permanent magnets 15 and core poles 16 are evenly spaced along an inner circumference of the rotor. A q-axis magnetic barrier 17 close to an air gap side is formed between one of the main permanent magnet poles and one of the core poles, and the q-axis magnetic barrier forms an uneven air gap with the outer circumference of the stator. A multi-layer arc magnetic barrier 19 close to an outer circumference side is formed between one of the surface-embedded main permanent magnet poles and one of the core poles, and a magnetic bridge 20 is formed between layers of the multi-layer arc magnetic barrier. A rectangular auxiliary permanent magnet 18 is provided between the q-axis magnetic barrier and the arc magnetic barrier close to the air gap.

Title: Process for cracking ammonia
Inventor: JULIE LOUISE ASHCROFT
IPC: C01B3/04
Filed: 2023-05-04
Abstract: Process for cracking ammonia to produce hydrogen comprising passing ammonia through one or more catalyst containing tubes 18 in a furnace 12. The tubes are heated by combustion of a fuel gas mixture, forming a flue gas containing nitrogen oxides capable of reacting with ammonia in the flue gas to form ammonium nitrate. The flue gas is cooled to below 170 °C while maintaining an amount of steam in the flue gas to prevent solid ammonium nitrate formation. The molar percentage of steam in the flue gas must be greater than the ratio of the equilibrium vapour pressure of water in an aqueous solution of ammonium nitrate to the minimum operating pressure of the flue gas. The prevention of the formation of solid ammonium nitrate and ammonium nitrite is intended to reduce the risk of explosion.

Title: Thermodynamic production and storage of energy from solar radiation collected with concave mirrors
Inventor: ZAGKOS IOANNIS
IPC: A01D7/06
Filed: 1997-08-21
Abstract: A system is constructed, consisting of a surface of concave shperical - parabolic mirror which is assembled of similar flat hexagonal cells. The system is permanently oriented to the South at an angle of 30 to 45 degrees and focuses the reflected solar radiation to a mobile steam boiler, the steam of which via flexible tubes is driven to a steam turbine and moves it. In this manner energy is produced from the solar radiation. Then, the steam is cooled in a closed circuit and returns to the steam boiler. The excess energy is stored, with the assistance of air liquefaction installations air and Dewar flasks, as liquefied air.

Abstract: This invention relates to spectacles in which are spectacle lens is connected to an individual component, for example a flange, by means of a fatening device. In the spectacle lens the two ends of a borehole are expanded into two borehole widenings which are engaged with a first protrusion on the flange and with a connecting element that is connected to a pin leading to the first protrusion. In addition, the flange has two further protrusions supporting themselves on the border of the spectacle lens, so that a four-point anchoring of the flange secured by the pin against pulling and by the additional protrusions against rotating is furnished on the spectacle lens and vice versa. A certain flange is suitable for given thicknesses and curvatures of the spectacle lens, because both on the front side and the back side of the spectacle lens it is not the front or back sides that define the gripping surfaces for the connecting element and first protrusion, but the borehole widening.

Abstract: A control circuit for a collectorless d.c. motor, without a commutation sensor, and comprising a stator with a multiphase system and a permanent-magnet rotor. The commutation state of the motor depends on the voltages induced in the stator windings. A comparison signal is generated which indicates whether the sign of that winding voltage which is not connected to a direct current source by means of the circuit electronic switching elements is in conformity with a predetermined sign which depends on the instantaneous commutation state. This comparison signal is inhibited during those time intervals in which transient effects which may cause spurious zero crossings occur in the windings as a result of the electronic switching elements being turned off. The switching elements are always switched one commutation step further if the comparison signal does not have the appropriate sign.

Abstract: An arrangement for suppressing audible noise occurring when audio equipment is switched on and off, in which a first electronic switch is connected to the output of an amplifier that has a negative feedback loop formed between the amplifier output and an inverting input of the amplifier. The output of the amplifier is connected to a load impedance through the first electronic switch. A second electronic switch is connected to a junction between the load impedance and the first electronic switch, and to the inverting input of the amplifier. A joint control line permits the two electronic switches to be turned on and off simultaneously. The two electronic switches can be connected in parallel through a feedback resistor in the negative feedback loop.
